Given numbers are 663,528,990,681,126

The least common multiple of numbers can be find using the prime factorization method or LCM formula.

The LCM of 663,528,990,681,126 is 2781258480.

Find LCM of 663,528,990,681,126 with Prime Factorization

Multiply the prime numbers at the bottom and the left side.

2 x 3 x 3 x 11 x 221 x 8 x 5 x 227 x 7 = 2781258480

Therefore, the lowest common multiple of 663,528,990,681,126 is 2781258480.

LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

Firstly, we have to find the product of all the numbers.

663 x 528 x 990 x 681 x 126 = 29737215668160

Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.

663 : 1, 3, 13, 17, 39, 51, 221, 663

528 : 1, 2, 3, 4, 6, 8, 11, 12, 16, 22, 24, 33, 44, 48, 66, 88, 132, 176, 264, 528

990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990

681 : 1, 3, 227, 681

126 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 42, 63, 126

3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 663,528,990,681,126, is 3.

Now, the common factors can be found like this.

663:3x 13x 17

528:2x 2x 2x 2x 3x 11

990:2x 3x 3x 5x 11

681:3x 227

126:2x 3x 3x 7

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2x 2x 3x 3x 3x 3x 11 = 3564

Therefore, the value for common factors is 3564.

Now that we have all the elements of the formula, we can plug them in to calculate the LCM.

LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

LCM = 29737215668160/(3x3564)

LCM = 29737215668160/10692

LCM = 2781258480

Thus, we can understand that the LCM of 663,528,990,681,126 is 2781258480.
